Stepper with additional functions to strengthen the arms and the chest

ABSTRACT

The present invention relates to a stepper with additional functions to strengthen the arms and the breast which includes a stepper and a pull rod both of which are fitted to a base. The stepper has two treads each of which has a front assembly pivotably connected to the base. The pull rod is pivotably connected to upright rods at front end of the base. Moreover, it is coupled with a movable handle at top thereof and a connecting rod at bottom thereof. The other end of the connecting rod is pivotably connected to the front assembly of the stepper. Accordingly, the pull rod, the connecting rod and the front assembly are coupled with one another. A position-limiting bar is inserted through the front end extending from the outer side of the upright rods.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a stepper with additional functions to strengthen the arms and the breast, and more particularly, to a device to combine the stepping device with the arm and breast strengthening trainer.

[0003] 2. Description of the Prior Art

[0004] As illustrated in FIG. 1, the earlier conventional mini stepper 1 has no components for the operator to hold on so that it's unsafe in using. Thereafter, an improved stepper 2, as shown in FIG. 2, is fitted with a handle 21 for the operator to hold on to keep body balance. However, the monotone stepping action can't reach the whole body exercise. Moreover, it tends to become boring for the operator. Thus, the persistence to use the exerciser will gradually disappear.

SUMMARY OF THE INVENTION

[0005] It is a primary object of the present invention to provide a stepper with additional functions to strengthen the arms and the breast in which the stepper and the arm and breast strengthening components can be dependently or independently operated. Therefore, the effect to combine the stepping exercise with the arm and breast strengthening training is achieved.

[0006] It is another object of the present invention to provide a stepper with additional functions to strengthen the arms and the breast through which a variety of exercises can be done so that a multifunctional device is attainable.

[0007] It is a further object of the present invention to provide a stepper with additional functions to strengthen the arms and the breast through which the body weight of the user serves as load when the operator takes the arm and breast strengthening training. Moreover, the whole design has the advantages of not occupying space and of being easy to operate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0019] First of all, referring to FIGS. 3 through 7, the present invention includes a stepper 4 and a pull rod 5 both of which are fitted to a base 3.

[0020] The stepper 4 has two treads 42 each of which has a front assembly 41 pivotably connected to the base 3.

[0021] The pull rod 5 is pivotably connected to upright rods 31 at front end of the base 3. Moreover, it is coupled with a movable handle 51 at top thereof and a connecting rod 52 at bottom thereof. The other end of the connecting rod 52 is pivotably connected to the front assembly 41 of the stepper 4. Accordingly, the pull rod 5, the connecting rod 52 and the front assembly 41 are coupled with one another. A position-limiting bar 521 is inserted through the front end extending from the outer side of the upright rods 31.

[0022] Moreover, the front assembly 41 of the stepper 4 comprises a transverse rod 411 and a mounting body 412. The transverse rod 411 of the stepper 4 is swiveled on a pivot 413 while the mounting body 412 thereof includes a top part 414 in pivotal connection with the connecting rod 52.

[0023] A turn shaft 421 of two treads 42 of the stepper 4 is fitted to two mounting bodies 412. Each of the treads 42 hat underneath an oil pressurized cylinder 43 the other end of which is fitted to the transverse rod 411 of the front assembly 41. A guide wheel 45 disposed between two treads 42 has a guide rope 44 extending around it and moving the treads 42 one after another.

[0024] Furthermore, as illustrated in FIG. 7, the pull rod 5 swivels on a turn pin 53 extending between two upright rods 31. The bottom end thereof is constructed as upside down U-form 54 so that the pull rod 5 and the connecting rod 52 are pivoted together by a pin 55.

[0025] Based on the above-mentioned components, the present invention has a few of application ways. As shown in FIG. 8, both hands hold the movable handle 51 while the both feet stand on the treads 42 for an exercise session. This provides only stepping function. As shown in FIG. 9, the both feet stand on the stepper 4 and keep unmoved while the both hands pull the movable handle 51 backwards. This pull force will bring the connecting rod 52 forwards to raise the stepper 4. Meanwhile, the body weight of the operator creates a load which must be overcome by both hands so that the effect to strengthen the arms and the breast is attainable. In addition, the stepping exercise and the exercise to strengthen the arms and the breast can be combined, as shown in FIG. 10. Accordingly, the coordination training of the body actions can also be achieved.

[0026] Many changes and modifications in the above-described embodiments of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims.
